🔧 Temporary Workarounds
Network Segmentation
allIsolate SCADA Data Server from untrusted networks and internet
Access Control Lists
windowsRestrict network access to Data Server ports using firewall rules
netsh advfirewall firewall add rule name="Block SCADA Ports" dir=in action=block protocol=TCP localport=PORT_NUMBERS
🧯 If You Can't Patch
- Implement strict network segmentation to isolate SCADA systems
- Deploy application whitelisting to prevent unauthorized code execution
🔍 How to Verify
Check if Vulnerable:
Check Data Server version in application interface or registry: HKEY_LOCAL_MACHINE\SOFTWARE\Schneider Electric\IGSS\DataServer\VersionCheck Version:
reg query "HKLM\SOFTWARE\Schneider Electric\IGSS\DataServer" /v VersionVerify Fix Applied:
Verify version is V15.0.0.22021 or later and test file write functionality is restricted📡 Detection & Monitoring
